Lip numbness is often referred to as lip paresthesias, which is the term used to describe any abnormal feeling in the lips, including numbness and tingling. There are a number of allergic reactions that can cause tingling or numbing sensations in the lips, but lip numbness isn't strictly caused by an allergic response. Conditions that cause symptoms of lip numbness range in severity. In the article that follows, several conditions that cause lip numbness or paresthesias will be discussed.
Hyperventilation is you breathe heavily and rapidly. It is usually brought on by anxiety or a stressful situation. When you are hyperventilating, you lose a large amount of carbon dioxide from their bloodstream, which in turn can cause further feelings of anxiety. A common symptom of hyperventilation is tingling or numbness in the hands, feet and lips. A bout of lightheadedness will then occur, sometimes followed by tetany or painful muscle twitching.
Sensory nerve damage, or peripheral neuropathy, can cause symptoms of numbness, tingling, pinching or pain. Often, when a person has neuropathy, numbness can begin in the feet and move up to the legs, making it difficult to walk and balance. The abnormal sensations are usually magnified at night while trying to sleep. Peripheral neuropathy is a very common ailment, affecting some 20 million people in the United States alone. In 30 per cent of cases of peripheral neuropathy, diabetes is the culprit.
Hypocalcaemia is caused by low levels of calcium in the bloodstream and can be the result of several underlying diseases, or the result of certain drug usage. In any case, hypocalcaemia can become a serious condition if it is not treated by a doctor. There are many different symptoms associated with this affliction, including tetany, parasthesias of the lips and tongue, aching muscles and muscle spasms. Diagnostic tests such as blood calcium and phosphate levels can be performed by doctors to diagnose hypocalcaemia in a patient.
This disorder is characterised by the constricting, or narrowing, of blood vessels in the fingers, toes, nose and ears. This narrowing of blood vessels, called vasospastic attacks, can cause spasms, tingling and pain in the affected areas. During a vasospasm, the skin can turn very white or even blue as the oxygen in the body diminishes. Raynaud's phenomenon can be a result of other diseases such as scleroderma or lupus. The tingling or numbing sensations can affect the hands and feet, nose, ear lobes and lips.
Ciguatera poisoning is caused by the consumption of a tropical finfish that is contaminated with ciguatoxins produced by dinoflagellates, which are tiny plants that smaller fish feed on. As the life cycle continues, larger fish will eat these contaminated smaller fish. As the toxin moves up in the food chain, it becomes more concentrated; therefore, bigger tropical reef fish have the highest concentration of ciguatoxins in their system. Symptoms include numb lips and tongue, nausea and vomiting, dizziness and even hallucinations. Ciguatera poisoning is rare, affecting fewer than 200,000 people in the United States population.
